Infective endocarditis (IE) is the infection of the endocardial surface (innermost layer - valves, chordae tendineae, and papillary muscles) of the heart. It usually refers to infection of one or more of the heart valves which may be native or prosthetic. The definition also includes infection on indwelling cardiac devices. Over time, the etiology, as well as causes of IE, have evolved and doubled in numbers because of a greater number of patients with indwelling cardiac devices and central lines. Some characteristic features have remained the same, including intravenous drug users (IVDU) and right-sided IE, fever, or peripheral signs of IE. However, there are instances where the clinical presentation is unique. Here we describe an unusual case of an IVDU patient developing acute decompensated heart failure following acute aortic regurgitation (AR) from IE without fever and right-sided heart or tricuspid valve involvement.Carotid artery dissection is an important cause of stroke, especially in the young. We present a 43-year-old lady, with a known background of headaches, who was referred to the Emergency Department with a headache, dilated pupil, and acute monocular blurring of vision. She was later found to have an internal carotid artery dissection (ICAD) with diffuse ipsilateral hemispheric involvement after being initially managed for atypical optic neuritis. This case report aims to provide further insight into an atypical presentation of a carotid artery dissection, with the intent of assisting the clinician in identifying such cases during the initial presentation.For intracranial meningiomas that metastasize extracranially, an oligometastatic state exists that is intermediate between incurable, widely metastatic disease and non-metastatic curable disease. Similar to oligometastatic cancer, aggressive local treatment of meningioma oligometastases is warranted, as it may be curable. We present a patient with multiply recurrent intracranial meningiomas over 19 years, with a transformation from grade I to grade II histology, with oligometastatic disease to the C5 vertebral body. Three years following definitive spinal stereotactic radiosurgery, she remains without evidence of other metastatic diseases. Our case highlights the oncologic concept that metastatic meningioma need not be widely disseminated and provides the clinical rationale for aggressive local treatment of an oligometastatic meningioma.Cardiac catheterizations and coronary angiography are minimally invasive methods for studying the heart and the coronary arteries, using iodinated radiocontrast agents which can cause acute kidney injury (AKI). Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARB) are widely used due to their well-established benefit in coronary artery disease and renal protection in diabetes mellitus. Renin-angiotensin-aldosterone system inhibitors can induce AKI in some patients.
This study analyzed the effect of radiocontrast media used for coronary angiography on renal function in patients with chronic kidney disease (CKD) stages 2-5 who also took ACE inhibitors/ARB medications.Information was collected from the electronic medical records of 116 cases to determine changes in serum creatinine following angiography. Result The average age of patients was 65.2 ± 12.3 years. There were 89 men (76.7%) and 27 women (23.3%). Six patients had documented ACE inhibitor discontinuation, and one patient had documented ARB discontinuation prior to their procedures. Based on the criteria of an increase in serum creatinine (SCr) by ?0.3 mg/dl within 48 hours, 19 cases (16.4%) had AKI. Based on the criteria of increasing in SCr to ? 1.5 times baseline, AKI developed in 2 cases (1.7%) on day 1, 4 cases (3.5%) on day 2, and 7 cases (6.0%) on day 3 after coronary angiography.
This study suggests that the continuation of ACE inhibitors/ARB does not appear to have any important effect or association with changes in renal function, within one-month post angiography in patients with CKD stages 2-5.

It presents clinically as a focal lower quadrant abdominal pain, usually in the absence of pyrexia, nausea, vomiting or change in bowel habit, and unremarkable laboratory markers. Due to its vague presentation, epiploic appendagitis may be mistaken for other more severe causes of acute abdominal pain like diverticulitis and appendicitis, thereby causing patients to undergo unwarranted management interventions and hospital stay. Epiploic appendagitis is usually diagnosed through imaging, most commonly computed tomography (CT). This condition is largely self-resolving and can be managed conservatively with nonsteroidal anti-inflammatory drugs (NSAIDs). Operative intervention is usually employed when symptoms persist or when complications arise. We present a case of epiploic appendagitis in a patient who presented with right lower quadrant pain initially misdiagnosed as acute appendicitis.Over the last half-century, radiation therapy has evolved to become one of the cornerstones of treatment for various types of cancers. It is estimated that more than 50% of patients with cancer are treated with radiotherapy. Patients with early stages of some cancers can even achieve a cure with radiotherapy alone. Radiation-induced heart disease is a well-recognized cause of mortality and morbidity in cancer survivors as a late complication of radiotherapy, often occurring more than a decade after radiotherapy. We describe a case of a middle-aged female who presented to the hospital with syncopal episodes. She was in remission from non-Hodgkin's lymphoma having received mediastinal radiotherapy 20 years, previously. Her initial workup such as laboratory investigations and 12 lead electrocardiogram were largely unremarkable. Cardiac monitoring over the course of the next few days was consistent with complete heart block with evidence of ventricular standstill. Her symptoms resolved following the implantation of a dual-chamber cardiac pacemaker.
